Kyocera Error F248 — What It Means & How to Fix It
By Ryan Green · Updated August 2026 · Independent guide · PrinterCare USA LLC (not affiliated with any printer manufacturer)
The F248 error on Kyocera printers is one of the more serious fault codes you can encounter, and it understandably causes frustration because it completely halts printing operations. This error specifically tells you that the printer's system firmware has become corrupted or unstable, either from a failed update, sudden power loss during a critical operation, or a hardware communication breakdown between core components.
The good news is that most F248 errors can be resolved without sending your printer in for service.
How to fix it — step by step
- Perform a Complete Power Cycle. Turn off your Kyocera printer using the power button on the control panel. Unplug the power cable from the back of the printer and wait for at least two full minutes—this allows residual power to drain completely and resets the volatile memory. Plug the printer back in, wait ten seconds, then turn it on again and observe whether the error clears.
- Check and Reseat All Internal Cables. If the power cycle did not work, turn off and unplug the printer again. Open the access panels on your specific Kyocera model (consult your user manual for the exact location) and visually inspect all ribbon cables and connectors between the main circuit board and the memory modules. Gently but firmly reseat each cable by disconnecting and reconnecting it to ensure solid contact. Do not force any connectors, as this can cause permanent damage.
- Access the Service Menu to Check Firmware Version. Power on the printer and navigate to the Settings or Administration menu on the control panel touchscreen. Look for a Service Information or System Information option and select it to view your current firmware version number. Write down this version exactly as displayed. If your printer appears to be running an unusually old or mismatched firmware version, this strongly suggests corruption.
- Attempt a Firmware Reset from the Control Panel. On most Kyocera models, you can access a Reset or Restore Defaults option in the Administration menu. Navigate to Settings, then look for Maintenance or System Tools, and select Restore Factory Settings or Reset System. Confirm this action when prompted. The printer will restart and reload its baseline firmware from internal read-only memory, which often resolves F248 errors caused by RAM or cache corruption.
- Clear the Printer's NVRAM and Memory Cache. If the standard reset did not work, power off the printer completely. Many Kyocera models have a small reset button (often recessed) on the back panel near the power connector—consult your manual to locate it. While the printer is unplugged, press and hold this reset button for ten to fifteen seconds using a straightened paperclip or similar tool, then release it. Plug the printer back in and power on to allow it to reinitialize all memory systems.
- Download and Install the Latest Firmware from Kyocera's Support Website. Visit the official Kyocera support page on your web browser and search for your exact printer model number (found on the rating label inside the rear door). Download the most current firmware file for your region and model to a Windows 11 or macOS computer. Connect your printer to your network via Ethernet or Wi-Fi, then follow Kyocera's step-by-step firmware update instructions, which typically involve uploading the file through the printer's web interface at its IP address.
- Verify Network Connectivity and IP Configuration. If you have a networked Kyocera model, go to Settings on the control panel and select Network Settings to confirm your printer has a valid IP address and stable connection. If the IP shows as 0.0.0.0 or if you see network error indicators, restart your network router and the printer together. A dropped network connection during a previous firmware operation can cause F248 errors on networked models.
- Contact a Professional for Firmware Reflashing. If you have completed all previous steps and the F248 error persists, the printer likely requires professional firmware reflashing or hardware-level repair. We offer remote diagnostic and repair services starting at forty-nine dollars, where a certified technician can reflash your printer's firmware, repair corrupted memory sectors, or identify failed hardware components. This service is typically faster and more affordable than shipping your printer to a depot.

Frequently asked questions
What does error code F248 actually mean on a Kyocera printer?
Error F248 indicates a system firmware error, which means the printer's main operating software has become corrupted, is missing critical files, or cannot communicate properly with the memory modules that store its settings and functions. This can happen due to interrupted firmware updates, sudden power loss, electrical surges, or hardware failures. It is a serious error because it prevents the printer from performing any operations until the firmware is restored or repaired.
Is the F248 error usually a hardware problem or a software problem?
In most cases, F248 is a software or firmware issue that can be resolved without replacing hardware. However, if basic resets and firmware updates do not clear the error, it may indicate failing memory chips or a corrupted main circuit board, which would require professional repair or component replacement. Starting with the simpler software solutions first is always the right approach before considering hardware service.
Can I fix the F248 error myself or do I definitely need to call a technician?
Many users can resolve F248 errors themselves by following the power cycle, reset, and firmware update steps outlined in this guide. However, if you are not comfortable accessing service menus or downloading firmware files, or if you have already tried these steps without success, professional help is the best option. A technician can perform advanced diagnostics and repair work that goes beyond what standard user troubleshooting can accomplish.
Will performing a factory reset erase all my saved print settings and network configuration?
A factory reset or system restore will clear many custom settings, address book entries, and network configurations depending on your printer model. Before resetting, write down any important network settings (IP address, security settings) or custom job settings that you rely on regularly. After the reset completes successfully and printing is restored, you can manually reconfigure these settings, and most users find this takes only a few minutes.
